Churn ROI Calculator
TL;DR
The ROI of reducing churn is the recovered recurring revenue net of tooling cost. Recovered MRR/month = current MRR × monthly churn rate × churn reduction; multiply by 12 for the annualized run-rate. Net gain = recovered annual revenue − annual plan cost. Because churned revenue compounds, even a small relative reduction in churn typically pays for retention tooling many times over.
Churn reduction is relative: cutting a 3% monthly churn by 20% leaves it at 2.4%. Saving even a fraction of at-risk MRR compounds over a year.

How to calculate churn ROI
Recovered MRR / month = current MRR × monthly churn rate × churn reduction. Multiply by 12 for the annualized recovered revenue. Subtract the annual cost of the tool to get net gain, and divide recovered revenue by plan cost for the ROI multiple.
Why small churn reductions matter so much
Churned revenue does not leave once — it leaves every month it goes unaddressed. A relative reduction of even 15–20% in monthly churn protects a recurring stream that compounds across the year, which is why retention tooling usually returns many times its cost.
From estimate to action
This calculator gives the headline math. The harder part is knowing which accounts to save — that is what RetentionLens adds on top of Stripe-native metrics: predictive churn-risk scoring and customer health scores that turn the reduction assumption above into a prioritized list of accounts to keep.
Frequently asked questions
How do you calculate the ROI of reducing churn?
Estimate the MRR you lose to churn each month (MRR × monthly churn rate), apply the relative reduction you expect (e.g. 20%), and annualize: recovered annual revenue = MRR × churn × reduction × 12. ROI is that recovered revenue net of the annual cost of the tool you used to achieve it.
What counts as a realistic churn reduction?
It varies by business, but a relative reduction of 10–25% from better-targeted retention is a defensible planning range. The calculator uses a relative reduction: cutting a 3% monthly churn by 20% leaves it at 2.4%, not 0.6%.
Why annualize the recovered revenue?
Churned MRR is lost every month it persists, so the impact compounds. Annualizing the recovered run-rate gives a fairer picture of the value than a single month, and matches how plan costs are usually evaluated.
Which plan should I compare against?
The calculator suggests the RetentionLens plan that matches your MRR — Starter (free) under $10k MRR, Growth at $59/mo under $50k, Scale at $229/mo above that — and nets the recovered revenue against that cost.
